[0002] Mining underground loaders are mainly suitable for loading, transporting, and unloading materials in non-explosive environments, such as mine roadways and other small tunnels. They are particularly well-suited for working environments with short transport distances, high emission requirements, narrow and low operating sites, and muddy conditions. In recent years, the variety of mining loader models has been increasing, with each model having different frame heights and widths, and slight structural variations. Therefore, during the assembly process, it is necessary to design and manufacture support fixtures of different specifications, heights, and load-bearing capacities, increasing tooling costs and management complexity. Furthermore, the unloading of the entire loader requires crane lifting, consuming significant time and manpower, and posing serious safety hazards.

[0026] See Figures 1-3 The present invention relates to a heavy-duty hydraulic support device, comprising a front support mechanism 1 and a rear support mechanism 2 arranged at the front and rear.

[0027] The front support mechanism 1 includes a front base 11 and a plurality of front support cylinders 12 vertically arranged on the front base 11. The front support cylinders 12 are slidably arranged on the front base 11 via rails 4. In this embodiment, two sets of front support cylinders 12 are provided, and the front support cylinders 12 are two-stage cylinders, which can ensure that the lifting height of the front support cylinders 12 is low enough. The lifting height range of the front support cylinders 12 is 370mm~670mm.

[0028] The rear support mechanism 2 includes a rear base 21 and a plurality of rear support cylinders 22 vertically arranged on the rear base 21. The rear support cylinders 22 are slidably arranged on the rear base 21 via a track 4. In this embodiment, two sets of rear support cylinders 22 are provided, and the rear support cylinders 22 are single-stage cylinders. The lifting height range of the rear support cylinders 22 is 470mm~750mm.

[0029] The support heights of the front support mechanism 1 and the rear support mechanism 2 are adjustable, allowing the support device to adapt to different heights of different models of loader frames. In other embodiments, more sets of front support cylinders 12 or rear support cylinders 22 can be set according to the structure of the loader. It should be ensured that the lifting height of the front support cylinder 12 is less than that of the rear support cylinder 22. While meeting the assembly requirements of the loader, it can also ensure that the loader can drive directly forward away from the support device after assembly, thus completing the loader's roll-off without the need for a crane. This saves a lot of time and manpower, improves work efficiency, and significantly enhances work safety.

[0030] Because the front and rear ends of the loader have different widths, the length of the front base 11 is set to be less than the length of the rear base 21 to avoid unnecessary material waste. To accommodate the different support positions resulting from the varying widths of different loader frames, the front support cylinder 12 and rear support cylinder 22 are adjusted by cylinder spacing adjustment mechanisms mounted on the front base 11 and rear base 21, respectively. These cylinder spacing adjustment mechanisms include a horizontal adjustment cylinder 3, whose two ends are hinged to the front base 11 and front support cylinder 12, or to the rear base 21 and rear support cylinder 22, respectively. Adjusting the horizontal position of the front support cylinder 12 or rear support cylinder 22 on the corresponding base changes the spacing between the cylinders. In this embodiment, the distance adjustment range between the two sets of front support cylinders 12 is 740mm~1140mm, and the distance adjustment range between the two sets of rear support cylinders 22 is 2500mm~2900mm. In other embodiments, the horizontal adjustment cylinder 3 can be replaced with an electric pusher cylinder, which can also perform the cylinder spacing adjustment operation.

[0031] The support height range and cylinder spacing range of the front support mechanism 1 and rear support mechanism 2 given in this embodiment were obtained by measuring the overall dimensions of each existing loader and analyzing the support points to statistically determine the required height and distance of the support fixtures. This led to the design and manufacture of a heavy-duty hydraulic support device that can meet the assembly requirements of a full range of mining loaders. This effectively satisfies the high quality requirements, high assembly efficiency, and good safety performance of various underground loader models and types. The application of this hydraulic support device not only meets production needs but also has strong versatility, applicable to the assembly of a series of mining loaders. It significantly improves operational efficiency and safety, reduces the labor intensity of workers, and saves the company tooling costs and manufacturing costs.

[0032] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
